Use ABS pipe and a leaf blower to make a powerful shooting machine. We used regular ping pong balls and 1½” styrofoam balls to show the vortex effect and how the shape of the ball makes the ball come out at different speeds.
We can use different sizes of pipes and various balls to get different results.
